What's the difference between muscle and myotome?

Muscle


Definition:

  • (n.) An organ which, by its contraction, produces motion.
  • (n.) The contractile tissue of which muscles are largely made up.
  • (n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
  • (n.) See Mussel.

Myotome


Definition:

  • (n.) A muscular segment; one of the zones into which the muscles of the trunk, especially in fishes, are divided; a myocomma.
  • (n.) One of the embryonic muscular segments arising from the protovertebrae; also, one of the protovertebrae themselves.
  • (n.) The muscular system of one metamere of an articulate.

Example Sentences:

  • (4) Parasagittal sections of the caudal myotomes of 10.5-d-old embryos showed that expression of contractile proteins preceded the expression of myogenin or MyoD and, when coexpressed, MHC and myogenin did not co-localize within all the cells of the myotome.
  • (5) "Ventral nerves" are seen on the midmedial surface of each myotome.
  • (6) The dermatomal and myotomal dissociation has been well-documented on the ipsilateral side, but involvement of the contralateral side is rare.

  • (9) The map may be important for the proper control of the many muscles arising from the myotomes in amniotes because it facilitates the development and evolution of motor systems in which anatomically and functionally different muscles have spatially separate motor pools in the cord.
  • (10) Using isoform-specific 35S-labeled antisense cRNA probes for in situ hybridization, we have detected BCK mRNAs in embryonic mouse and chick myotomes, the first skeletal muscle masses to form in developing embryos.
